"Check Disk for Errors" & "hard drive needs to be formatted" errors

I'm getting a lot of "Check Disk for Errors" and "this hard drive needs to be formatted before it can be used" error messages when plugging my external usb hard drives into my home pc which uses windows 7. I don't get any of these messages when I plug the same hard drives in at any of a number of pcs at work which use windows xp. Any ideas on why this is happening only with windows 7? I'm also getting a lot of disconnects and reconnects on these devices but again only on windows 7.

Thanks in advance for any advice you can give...

DR

Welcome

I would do the ck disk. If you still get the notices, I would be concerned about HD failure. Take the HD diagnosis.
